Application al a April 6', 1920. Serial No. 100,008.

Our invention relates to drawing frameform of feeder and an automaticstop therefor.

Figure 1 is a side elevation the automatic stop;

Figure 2 shows the stop and electric c rcuits therefor; v 0

Figure 3 shows an elevation of the recoming cans and shift mechanismtherefor;

- Figure 4 is a plan view of Figure 3; 7

Figures 5, 6, and 7 show right and left side views of the feeder anddetails-of'th electric contact;

Figure 8 is a plan view. of the feeder; 6 Figures 9, 10, and 11 showdetails of the feeding rolls; and 4 Figure 12 is a plan view of amodified form of feeder.

In Figure I, we have shown at A the drawing machine in outline, therebeing no novelillustrating tv in that'machine itself claimed herein. At

the left we show at'B one end of the novel form of lfeederwe havedevised for bringing the material .to and delivering it into themachine, Above the machine and mounted on a bracket C is the box-Ccontaining the electro-magnets and battery of theautomatic stopmechanism, the same being shown more fully in Figure 2.

The feeder aforesaid has" for its support ing frame a series ofparallelbeams B (Figs. 5, 6, 8. and 9), each mounted at one end on abracket B projecting frbm the left side of the machine'as shown inFigure 1. These beams are shown inside view in Figures 5" and 6, ofwhich the former is taken from the D, I) and 1) (Figs. 8 and 9),.whichextend clear across the frame. A cross-section of feed roll D isshown inFigure 10, from' which it appears that the ribs between the succeedinggrooves are square-edged and the grooves themselves square-edged at thebottom; Thisgives the rolls a better bite. on

the slivers of hemp which they feed forward as they, rotate." Theseveral bearings for the. rolls,'of,vvhi 'ch there are three shown, oneat each end and one in between, are all alike and the description of oneapplies to-all.

This bearing (see Figure 10) i comprises a hracketE mounted on the upperside of a beam 3, but insulated therefrom electrically bly a block e.The bracket E is somewhat L- s aped and in its upper end is journalledthe shaft of the roller y .an insulating bushing a (see Figure 9). Bythismeans each roller is insulated from the rest of the machine, but isconnected to form one terminal of an electric circuit by means of aspring-pressed and insulated contact pin G that bears constantl againsta washer g on the left hand J end 0 each roller (see Figure'l). Thefirst grooved roller D is rotated by means of a sprocket :chain 1),driven by ashaft of the main machine, and an insulated sprocket wheel hon the shaft of the roller (see Figure 8). The second roller D is drivenfrom the and sprocket wheels h and It", while the third roller 1) issimilarly driven from the sec 0nd one D by a sprocket chain 6 andsprocket wheels h and h all of the sprocket Clttl s being-insulated fromthe rollers.

The. aforesaid brackets E also support a non-rotating shaft F-paralleland closely adj acent tdeach. of the rollers D, D and 1) respectively.The shafts F are not insulatedfrom the brackets E. At each point alongthe grooved rollers where a line of hemp is to be fed, a pair of curvedyokes K, K'are mounted on stationary shaft F and carry a short barrelpressure roll P. The roller P has a short shaft at each end resting bygravity in the hot-tom of a notch formed in the upper end of eaclr yokeK. The curve in yoke K allows it to encircle one-half of the groovedroller and bring the pressure roller P directly above it. The outer edgeof the curved portion of each yoke K is also flattened to a thin edge toform a converging channel for the hemp as it approaches the groovedroller. In 0 ration a line or sliver of'hemp of a width a out equal tothe length of a pressure roller P is drawn vertically upward from a pileadjacent to the machine and passes over one of the grooved I i-occurswhenever the sliver becomes bunched near the outer frame beam B and thenproceeds over rollers D and D to the carding machine, being upheld,between D and D, by a table S. Similarly a second sliver R at a pointnear the intermediate beam B .is also the upper or left hand beam Bmaking eight,

slivers in all that are fed to the carding machine. These are recombinedin the machine to'make four carded slivers that are finally deliveredfrom the machine into the fourreceiving cans, of which two are shown forillustration in Figure 4 marked'respectivelv T and T ,In Figure 12 amodified arrangement is shown wherein there are but two feed rollers,

- D andD, the intermediate one, D of Figure 8, being omitted. In thisarrangement there 'are, in all, four slivers started initially by rollerD at different points along its length, and passed over roller D to thecarding machine, while another four are started by roller D and passeddirectly therefrom to the machine. At each of the shortbarrel-shapedrollers P there is provided a scraper or cleaner N (see Figure 10) ofrubber, which bears diagonally and yieldingly on the feed roller to keepthe feeding edges of the roller ribs clear and at the same time preservethe electrical insulation of the roller.

'The automatic stopping of the machine is dependent on the absence ofthe fed material between any pressure roll P and its feed roller wherebythe two rolls, which form the opposite terminals of an electric circuit,come in contact and close that circuit. The closure of the circuitbrings into action an electromagnetic'belt-shifter which throws thedriving belt of the machine from the fast to the loose pulley and stopsit. The stopping also on one edge or is otherwise so disarrangcd thatthe two rollers come in contact. For example, in Figure 9 the fedmaterial is in its normal condition under the two rollers P, P at theright and the one roller P at the left.

- But of the remaining two rollers, the left hand one has no sliverunder it, so that it rests on the feed roller, while the one at theright has been tilted up at one end by the bunching of the sliver alongits left edge. thereby bringing the right hand end of roller P intocontact with the feed roller.

machine will be stopped.

The details of the stopping mechanism are shown in Figure 2. The fastpulley is marked In either case the 11, the loose pulley 10, andthe belt12. The v shifter fork 1 3 is mounted on the end of a which drops innotch 15 i'nthe upper edge of the rod and is held against the pressureof spring 17. The circuit which is closed by the aforesaid contact ofthe pressure and feeding rollers may be traced from battery Z to thecontrolling rollers and thence by wire 40 to relay magnet Y back to thebattery, switch 20 being closed and shunt-resistance 19 serving toadjust the strength of the magnet. The action of relay Y closes thecircuit of the heavier latch-lifting magnet X which may be adjusted instrength by the switch 23 that either puts resistance in series with Xor short-circuits said resistance. The local circuit for magnet X isfrom battery Z to contacts 24: to X and t en either through resistance18 or the short cir uit around it to the wire 42'and back to the batterythe switch 21 being closed. A switch 22 is provided for stopping themachine by hand, the hand closure of the circuit by switch 22 having thesame effect as the automatic closure thereof by the rolls.

The slivers are respectively delivered by the carder into a serles ofreceivers T, T, etc., which are kept in oscillation as described inapplication for patent by John Fliedner, filed January 2, 1926, SerialNo. 78,751. The mechanism for thus oscillating the receivers isindicated in Figures 3 and 4. Referring to those figures, the table T onwhich re-.

ceiver T rests carries a large gear wheel T which is slowly rotated by avertical shaft 50 through a train of reducingvgears 51. The verticalshaft 50 is driven in periodically reversed directions by the bevelgears 52 and 53, which are periodically and alternately clutched to thehorizontal shaft 54, which is driven constantly by bevel gears on shaft55 which, in turn, is driven from the carder by a belt 56. The clutch isperiodicall shifted by a groove-wheel cam 57 on she t 58 which is drivenfrom shaft 54' by gearing 59. The clutch is marked 60 and its shiftlever62 has a pin that rides in the groove of cam 57.
